Abstract

본 발명의 레이저 프린터의 세로쓰기 제어장치 및 제어방법은 호스트 컴퓨터에서 가로쓰기로 출력되는 문자 및 숫자를 비롯한 각종 기호들의 코드화된 데이타를 레이저 프린터가 세로쓰기의 코드화된 데이타로 변환함으로써 호스트 컴퓨터가 프린트할 코드화된 데이타를 세로쓰기의 코드화된 데이타로 변환하지 않아도 레이저 프린터가 세로쓰기로 프린트할수 있도록 하는 것이다.The vertical write control device and control method of the laser printer of the present invention prints the host computer by converting the coded data of various symbols, including letters and numbers, which are output horizontally from the host computer into the coded data of the vertical write. This allows the laser printer to print vertically without converting the coded data to vertically coded data.

종래에는 사용자가 일일이 호스트 컴퓨터에 세로쓰기를 명령하여 문자, 숫자 및 각종 기호들을 세로쓰기의 코드화된 데이타롤 출력하도록 하거나 또는 변경하여 출력하도록 하여 세로쓰기를 하였으므로 사용자에게 많은 번거로움을 주는 문제점이 있었다.In the related art, a user writes a vertical write command to a host computer to output letters, numbers, and various symbols in a vertical write coded data, or changes and outputs a vertical write, thereby causing a lot of trouble for the user. .

본 발명은 호스트 컴퓨터(10)가 가로쓰기의 코드화된 데이타를 출력할 경우에 이를 레이저 프린터(20)가 호스트 버퍼(23)에 저장하고, 호스트 버퍼(23)에 저장되어 있는 코드화된 데이타의 라인수 및 각 라인의 데이타수를 판별하여 세로쓰기로 변환 및 임시버퍼(24)에 저장하고, 임시버퍼(24)에 세로쓰기로 저장되어 있는 코드화된 데이타에 대한 비트 맵 이미지를 폰트 롬(25)에서 찾아 이미지 버퍼(26)에 저장한 후 엔진 인터페이스부(27)를 통해 출력하여 세로쓰기로 프린트하게 함으로써 세로쓰기를 원하는 사용자의 요구조건을 충족시킬수 있고, 또한 호스트 컴퓨터에 세로쓰기로 명령하거나 또는 가로쓰기의 코드화된 데이타를 일일이 세로쓰기로 변환하지 않아도 된다.According to the present invention, when the host computer 10 outputs horizontally coded data, the laser printer 20 stores the coded data in the host buffer 23 and the line of the coded data stored in the host buffer 23. The number and the number of data on each line are converted to vertical writing and stored in the temporary buffer 24, and the bitmap image of the coded data stored vertically in the temporary buffer 24 is stored in the font ROM 25. By storing the image buffer 26 in the image buffer 26 and outputting the image through the engine interface 27 to print vertically, the user's requirement for vertical writing can be satisfied, and the host computer can be instructed to vertically write or You do not have to convert horizontally coded data to vertical writing.

Claims

A central processing unit 21 for controlling the overall operation of the laser printer 20, a parallel / serial interface 22 for serially converting data output in parallel from the host computer 10, and a host computer 10 The host buffer 23 for storing and outputting the coded data outputted by the central processing unit 21 and the coded data stored in the host buffer 23 are stored in the central processing unit 21. Temporary buffer 24 which is converted into vertically coded data and stored and output under the control of the character, and a font for storing the bitmap image of the coded data in advance and outputting the same under the control of the CPU 21. An image buffer 26 for storing and outputting a ROM 25 and a bitmap image of coded data stored in the temporary buffer 24 under the control of the CPU 21, and the image buffer ( At 26) Vertical control device of the laser printer, characterized in that the configuration of the bitmap image that is output to the engine interface unit (27) for printing the interface.

A first step of determining the number of lines of the horizontally coded data output by the host computer 10 and the maximum number of characters of the lines, and converting the horizontally coded data to the horizontal line by reading the columns in the order of the columns; The second step of storing the carriage return and line feed when the horizontal writing is completed, and converting the horizontal writing coded data to the vertical writing, and then ending the vertical writing when the last coded data read is the end of the data. And a third step of storing the end of data in the laser printer.

3. The method of claim 2, wherein the second step inserts a space after each character while converting the coded data of the horizontal writing into vertical writing.

3. The method of claim 2, wherein the second step inserts a space when the transcoded data is a carriage return and a line feed.
